Will try to address most points from this thread...

I guess you really have to draw the line between competence in something truly beneficial...and delusional (being a leader for the sake of being a leader).
Someone could be excellent at giving talks, winning arguments, charm etc but to what end? To further perpetuate a damaging high control group? If wisdom at large and humility is taken out of the equation then a so called "good leader" may just be good for getting followers and nothing much else. Then what happens when this competent person is challenged and called out for the lack of tangible "fruits"? The disguised ego takes over and it becomes more about them than the purpose to give to the group. They start to see the people they "serve" as their own possessions, and God forbid anyone tries to steal them away (denounce the leader's direction) since the leader's sense of self worth is built upon this ongoing adoration/respect. Hence the reason why many exJWs who were in positions of influence in the org struggle to adapt to "normal conditions" outside it - they still crave the ego stroking of being a somebody (often trying to gratify it in other ways).
That's not to say that the motives are always bad. All I know is that I have swayed between various emotions, and still do - from desiring to help people (a creative and zealous altruism), to other humbling feelings of realising the gaping holes in my own life which brings me crashing back to earth again :)
